MEDICATED INSOLE FOR FOOTWEAR.

i-,iigraa Specification of Letters Patent.l

Patented Oct. 13, 1914.

Application led March 18, 1914. Serial No. 825,600.

-enable others skilled in the art -to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and guresof reference marked thereon, which form a part ofthis specication.

This invention relates to new and useful improvements in insoles forshoes, footwear, etc., and comprises a simple and. efficient de vice ofthis nature, made preferably of the matted ber of the palmetto treewhich has been suitablytreated with tannic acid.

I have illustrated in the drawing, forming a part of this applicationviews of insoles made of palmetto and in which:

Figure 1 is a plan view of a sole, and Fig.

2 is an enlarged .detail view of a portion of one of the solesshowing-the manner of the intersecting hairlike bers of the palmetto.

In treating, the ber A, before beingmade up into -insoles, havingbacircumferential' binding B of cloth stitched thereto, or other purposefor which it is to be used, issprayed or otherwise treated witha mixtureof coal oil I(kerosene) and4 oil of myrbane, prefer ably in theproportions of one gallon of coal oil toone ounce of myrbane. Thismixture as it acts upon the ber which naturally con- ,tains aconsiderable amount of tannic acid,

incorporated within the ber, will in 'no way interfere with theelasticity of the ber or itsl usefulness as an insole or as aller forinattresses or other purposes cfor which 5etc., and will impartanagreeable it maybe employed.. After the treatment of the insole with themixture of oil of myrbane and coal oil, the palmetto ber remainsimpregnatedtherewith without aifecting'the tannic acid which exists inthe ber, the tannic acid serving to repel' insects by reason of itsbitterness as well as serving to preserve the ber in a similar manner aswould be the effect of the tannic acid upon tanning hides in themanufacture of leather.

}\By the provision of insoles made of the palmetto ber, when treatedinthe manner described, I have found that the burning and sweating offeet will be` revented, a

soft means to cushion the feet will be afforded and any impurities whichmayV be given o` throu h the pores of the feet vwill be absorbed ytheber, the feet beingke t xcool 'in hot weather and warm in co dweather. lThe ber, which isoflight'texture and elastic; will be airyandfa nonconductor of heat-and coldand will'produce a perfectly healthyinsole, capablel of being Awashed and dried repeatedly without in anyway injuring the ber. o The palmetto ber any insects, such as redv bugs,j-iggers, fleas,

` fragrance to the foot and `shoe of the wearer.

What I claim to benew is:

An insole 'for shoes and other footwearl made up of a niatted ber ofthebark of the palmetto tree, containing tannic acid in its makeup, andimpregnated with a ture of coal oil, and oil of myrbane, as set forth.
